The Moses Lake Reservoir in Washington is pretty important for BMW: all the sustainable carbon fiber they use for their i cars is made there. But the material's journey ends in Germany. That's a long way to go, and this is how it's done.

After the raw material is made, it's transferred to Bavaria where the carbon fiber textile is weaved and pressed before making it to the assembly lines in BMW's Leipzig factory.

If you think about it, this is the sort of carbon footprint Tesla would like to achieve by building its gigafactory powered by renewable energy. We'll see if they succeed, but for now, BMW remains one giant step ahead of basically everyone in the business.
